Super slow Linux VMs

Hello Everyone,


I have created an Ubuntu VM on my unraid but its super slow. I have everything pinned to core0 and my VM is pinned to core 1-3. I got it to install after having to reboot the VM like 4 times since it would get stuck each time. Once it was installed I was able to install anydesk on it and it worked faster than VNC. The problem is that opening anything makes my 3 cores go to 90%+ and it will stay there. The program (most times just firefox) wouldnt even finish opening and I would have to restart the VM. I uninstalled Ubuntu thinking it was the OS thats the problem and when I tried Linux Mint im getting sort of the same thing. The installation had no problems. I couldnt get anydesk running on it but thats fine. When I open firefox it pins my cores to 70%+ and firefox hasnt even loaded the home page in 20 minutes. I have 5GB of ram assigned to it.


Does anyone know what the problem could be?

Diagnostics would also help

I think I figured it out after 2 hours more of tinkering. The initial ram was set to 1GB and the max to 5GB. I’m guessing I was running on 1GB this whole time. Once I set both to 10GB it started to work better. Doesn’t feel like a 3 core 10GB ram computer yet though. My 10 year old apple with 2 cores 4GB runs better.


Now I’m trying to run a game on it to see what it can do.


I will post again if it’s still sluggish with the diagnostics.
